From my own personal experience
“I’ve personally noticed this while using my own car regularly in heavy city traffic. There was a time when I delayed a basic service by a few thousand kilometres, assuming it wouldn’t make much difference. Within weeks, the engine felt slightly rough and fuel efficiency dropped more than expected. A similar situation happened with a friend’s car as well, which clearly shows how small maintenance delays can impact long-term performance.”
